The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has expat packages installed that are affected by multiple vulnerabilities:

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for     m_groupSize. (CVE-2021-46143)

  - defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
    (CVE-2022-22824)

  - lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22825)

  - nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
    (CVE-2022-22826)

  - storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22827)

  - Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with     a nonzero XML_CONTEXT_BYTES. (CVE-2022-23852)

  - xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks     for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

  - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters     into namespace URIs. (CVE-2022-25236)

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-058 advisory.

    In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

    In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for     m_groupSize. (CVE-2021-46143)

    addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22822)

    build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22823)

    defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

    (CVE-2022-22826)

    storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22827)

    expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a     large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to     integer overflow. The highest threat from this vulnerability is to availability, confidentiality and     integrity. (CVE-2022-23852)

    Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. (CVE-2022-23990)

    A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences (for example, from start tag     names) to the XML processing application on top of expat can lead to arbitrary code execution. This issue     is dependent on how invalid UTF-8 is handled inside the XML processor. (CVE-2022-25235)

    A flaw was found in expat. Passing one or more namespace separator characters in the xmlns[:prefix]     attribute values made expat send malformed tag names to the XML processor on top of expat. This issue     causes arbitrary code execution depending on how unexpected cases are handled inside the XML processor.
    (CVE-2022-25236)

    A flaw was found in expat. A stack exhaustion in doctype parsing could be triggered by a file with a large     number of opening braces, resulting in a denial of service. (CVE-2022-25313)

    An integer overflow flaw was found in expat. This issue affects the encoding name parameter at the parser     creation time, which is often hard-coded (rather than user input), takes a value in the gigabytes to     trigger, and on a 64-bit machine. This flaw can cause a denial of service. (CVE-2022-25314)

    An integer overflow was found in expat. The issue occurs in storeRawNames() by abusing the m_buffer     expansion logic to allow allocations very close to INT_MAX and out-of-bounds heap writes. This flaw can     cause a denial of service or potentially arbitrary code execution. (CVE-2022-25315)

    A vulnerability was found in expat. With this flaw, it is possible to create a situation in which parsing     is suspended while substituting in an internal entity so that XML_ResumeParser directly uses the     internalEntityProcessor as its processor. If the subsequent parse includes some unclosed tags, this will     return without calling storeRawNames to ensure that the raw versions of the tag names are stored in memory     other than the parse buffer itself. Issues occur if the parse buffer is changed or reallocated (for     example, if processing a file line by line), problems occur. Using this vulnerability in the doContent     function allows an attacker to triage a denial of service or potentially arbitrary code execution.
    (CVE-2022-40674)

    In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in     XML_ExternalEntityParserCreate in out-of-memory situations. (CVE-2022-43680)

Tenable has extracted the preceding description block directly from the tested product security advisory.

  - An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a     potentially exploitable crash. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and     Thunderbird < 91.7. (CVE-2022-26381)

  - When resizing a popup after requesting fullscreen access, the popup would not display the fullscreen     notification. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and Thunderbird < 91.7.
    (CVE-2022-26383)

  - If an attacker could control the contents of an iframe sandboxed with <code>allow-popups</code> but not     <code>allow-scripts</code>, they were able to craft a link that, when clicked, would lead to JavaScript     execution in violation of the sandbox. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and     Thunderbird < 91.7. (CVE-2022-26384)

  - Previously Firefox for macOS and Linux would download temporary files to a user-specific directory in     <code>/tmp</code>, but this behavior was changed to download them to <code>/tmp</code> where they could be     affected by other local users. This behavior was reverted to the original, user-specific directory.
    <br>*This bug only affects Firefox for macOS and Linux. Other operating systems are unaffected.*. This     vulnerability affects Firefox ESR < 91.7 and Thunderbird < 91.7. (CVE-2022-26386)

  - When installing an add-on, Firefox verified the signature before prompting the user; but while the user     was confirming the prompt, the underlying add-on file could have been modified and Firefox would not have     noticed. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and Thunderbird < 91.7.
    (CVE-2022-26387)

  - Removing an XSLT parameter during processing could have lead to an exploitable use-after-free. We have had     reports of attacks in the wild abusing this flaw. This vulnerability affects Firefox < 97.0.2, Firefox ESR     < 91.6.1, Firefox for Android < 97.3.0, Thunderbird < 91.6.2, and Focus < 97.3.0. (CVE-2022-26485)

  - An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploitable sandbox     escape. We have had reports of attacks in the wild abusing this flaw. This vulnerability affects Firefox <     97.0.2, Firefox ESR < 91.6.1, Firefox for Android < 97.3.0, Thunderbird < 91.6.2, and Focus < 97.3.0.

The version of AOS installed on the remote host is prior to 5.20.3.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.3.6 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - In Cyrus SASL 2.1.17 through 2.1.27 before 2.1.28, plugins/sql.c does not escape the password for a SQL     INSERT or UPDATE statement. (CVE-2022-24407)

  - A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed     by OpenLDAP's slapd server, to trigger an assertion failure. The highest threat from this vulnerability is     to system availability. (CVE-2020-25709)

  - A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious     packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this     vulnerability is to system availability. (CVE-2020-25710)

The remote NewStart CGSL host, running version MAIN 6.02, has firefox packages installed that are affected by multiple vulnerabilities:

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This     vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2021-4140)

  - crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in     Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in     the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks     are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a     logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are     affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. (CVE-2021-32810)

  - Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.14, Thunderbird < 78.14,     and Firefox < 92. (CVE-2021-38493)

  - During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in     memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,     Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)
